RESUMEN
BACKGROUND: This study aimed to examine the reporting quality of existing economic evaluations for negotiated glucose-lowering drugs (GLDs) included in China National Reimbursement Drug List (NRDL) using the Consolidated Health Economic Evaluation Reporting Standards 2013 (CHEERS 2013). METHODS: We performed a systematic literature research through 7 databases to identify published economic evaluations for GLDs included in the China NRDL up to March 2021. Reporting quality of identified studies was assessed by two independent reviewers based on the CHEERS checklist. The Kruskal-Wallis test and Mann-Whitney U test were performed to examine the association between reporting quality and characteristics of the identified studies. RESULTS: We have identified 24 studies, which evaluated six GLDs types. The average score rate of the included studies was 77.41% (SD:13.23%, Range 47.62%-91.67%). Among all the required reporting items, characterizing heterogeneity (score rate = 4.17%) was the least satisfied item. Among six parts of CHEERS, results part scored least at 0.55 (score rate = 54.79%) because of the incompleteness of characterizing uncertainty. Results from the Kruskal-Wallis test and Mann-Whitney U test showed that model choice, journal type, type of economic evaluations, and study perspective were associated with the reporting quality of the studies. CONCLUSIONS: There remains room to improve the reporting quality of economic evaluations for GLDs in NRDL. Checklists such as CHEERS should be widely used to improve the reporting quality of economic researches in China.

To maintain a comfortable indoor living environment in low latitude or tropical regions, humans consume significant amounts of electrical energy in air conditioning, leading to substantial CO2 emissions. Passive daytime radiative cooling (PDRC) allows objects to cool down during the daytime without any energy consumption by dissipating heat through the atmospheric transparency window (8-13 µm) to outer space, which has garnered significant attention. However, the practical applications of common PDRC materials are hindered by their poor optical selectivity and high-reflective silver backing. Additionally, the availability of artificial photon emitters with complex structures and excellent performance is also limited by their high cost. Herein, a novel multilayer prismatic photonic metamaterial film without any silver reflector, easily scalable and produced by a roll-to-roll method is demonstrated, which exhibits ≈96.4% sunlight reflectance (0.3-2.5 µm) and ≈97.2% emissivity in mid-infrared (IR) (8-13 µm). At an average solar intensity of ≈920 W m-2, it is on average 6.8 °C below ambient temperature during the day and theoretically yields a radiative cooling power of 88.9 W m-2. Furthermore, the film exhibits excellent hydrophobicity, superior flexibility, and robust mechanical strength, providing an attractive and viable pathway for practical applications addressing the pressing challenges of climate and energy issues.
RESUMEN
Background: Postoperative delirium (POD) is a common complication following cardiac surgery and increases postoperative morbidity and mortality. Intraoperative electroencephalogram (EEG) burst suppression suggests excessively deep anesthesia and predicts POD. Use of remimazolam provides a stable hemodynamic status and an appropriate depth of anesthesia. We aim to assess remimazolam administered for anesthesia and sedation in elderly patients having cardiac surgery. Methods: This is a randomized controlled clinical trial with noninferiority design. A total of 260 elderly patients aged equal to or greater than 60 years undergoing cardiac surgery will be randomly allocated to receive remimazolam or propofol (1:1) for general anesthesia and postoperative sedation until extubation. The primary outcome is the cumulative time with EEG burst suppression which is obtained from the SedLine system. The noninferiority margin is 2.0 min. The secondary outcomes include the POD occurrence within the first 5 days postoperatively and the duration of perioperative hypotension. Discussion: This noninferiority trial is the first to evaluate the effect of perioperative remimazolam administration on EEG burst suppression, POD occurrence, and duration of hypotension in elderly patients who undergo cardiac surgery. Trial registration: Chinese Clinical Trial Registry (ChiCTR2200056353).
RESUMEN
Chemodynamic therapy (CDT) is a novel tumor treatment method by using hydroxyl radicals (â¢OH) to kill cancer cells. However, its therapeutic effects are strictly confined by the short lifespan of â¢OH and reduced â¢OH generation speed. Herein, an effective CDT is achieved by both improving â¢OH lifetime and long-lasting generating â¢OH through intraparticle electron transfer within heterogeneous nanoparticles (NPs). These heterogeneous NPs are composed of evenly distributed Cu and Fe3O4 (CFO NPs) with large interaction interfaces, and electrons tend to transfer from Cu to Fe3O4 for the appearance of ≡Cu2+ and increase in ≡Fe2+. The generated ≡Cu2+ can interact with GSH, which prolongs the lifespan of â¢OH, produces ≡Cu+ for higher speed â¢OH generation with H2O2, and induces cell ferroptosis for tumor therapy. The improved ≡Fe2+ can also improve the â¢OH release under H2O2 until Cu is depleted. As a result, a sustainable â¢OH generation is achieved to promote cell apoptosis for effective tumor therapy. Since H2O2 and GSH are only overexpressed at tumor, and CFO NPs can degrade in the tumor microenvironment, these NPs are with high biosafety and can be metabolized by urine. This work provides a novel biomaterial for effective cancer CDT through intraparticle electron transfer.
RESUMEN
Calcium-overload-mediated tumor therapy has received considerable interest in oncology. However, its efficacy has been proven to be inadequate due to insufficient calcium ion concentration at the tumor site coupled with challenges in facilitating efficient calcium uptake by tumors, leading to unsatisfactory therapeutic outcomes. In the present study, calcium carbonate nanoshell mineralized ferric polydopamine nanoparticles (Fe-PDA@CaCO3 NPs) were prepared for achieving Ca2+-overload-mediated tumor therapy. Upon entering the tumor site, the pH-responsive CaCO3 layer, acting as a "Ca2+ storage pool", rapidly degraded and released high quantities of free Ca2+ within the weakly acidic environment. The Fe-PDA core, with its excellent photothermal conversion properties, could significantly increase the temperature upon exposure to near-infrared (NIR) light irradiation, thereby activating the TRPV1 channel and leading to a large influx of released Ca2+ into the cytoplasm. Furthermore, the exposed Fe-PDA core could react with the tumor-overexpressed hydrogen peroxide (H2O2) to efficiently produce hydroxyl radicals (â¢OH), significantly increasing intracellular reactive oxygen species (ROS) levels and thus inhibiting the activity of the Ca2+ efflux pump, resulting in a high intracellular Ca2+ concentration. Ultimately, the increase in calcium/ROS levels could disrupt mitochondrial homeostasis and activate the apoptosis pathway. The current work presents a promising approach for tumor therapy using photothermal-enhanced calcium-overload-mediated ion interference therapy and chemodynamic therapy.
RESUMEN
Aim: Atopic dermatitis (AD) often accompanies skin infections, and bacterial skin infections often cause persistent and worsening symptoms. In this study, we explored the key changes in the microbiota of AD patients, as well as the effects of different ages and the severity of rash on changes in the microbiota. Patients and Methods: A total of 95 AD patients and 77 healthy volunteers were recruited. The AD patients were divided into three groups based age and three groups according to the EASI score. Microorganisms collected from the skin were analyzed through 16S rRNA gene sequencing, revealing species diversity via α and ß diversity analyses. Species compositions were compared at the phylum and genus levels. The significance of skin microbiota at the genus level was assessed using the random forest algorithm. Finally, the impact of relationships between different microbial communities on the microbial community composition and the pathogenesis of AD was explored using Pearson correlation coefficients. Results: The species diversity of the skin microbiota in the AD group significantly decreased. Compared with that in the healthy volunteers (HV) group, the bacterial diversity in the two groups of samples significantly differed. Staphylococcus dominated the bacterial communities, and as AD symptoms gradually worsened, the abundance of Staphylococcus gradually increased. Among all bacterial genera with a relative abundance greater than 1%, Staphylococcus showed a negative correlation with other genera, and showed significant consistency in specimens from different age groups. Conclusion: Changes in the abundance of Staphylococcus in the skin bacterial colonies are the main cause of AD. Brevundimonas, Paracoccus, Corynebacterium, and Veillonella may serve as characteristic biomarkers for AD. These results indicate that altering the microbiota composition of the skin may aid in the treatment of AD.
RESUMEN
Drug-induced autoimmune-like hepatitis (DI-ALH) is a special clinical phenotype of drug-induced liver injury and has similar clinical features and laboratory test results to autoimmune hepatitis, and it is often difficult to distinguish them through liver biopsy. Therefore, correct differential diagnosis DI-ALH and autoimmune hepatitis is a crucial and difficult point in clinical practice. This article analyzes the research advances in the pathogenesis, clinical features, diagnosis and treatment, and prognosis of DI-ALH, in order to provide ideas for the diagnosis and treatment of such diseases among clinicians.

Objective:To analyze the release and distribution characteristics of Chinese medical insurance payment policies,and to provide reference for future policy formulation in the field of medical insurance payment construction.Methods: Content analysis method was used to construct a two-dimensional framework of "policy goals-policy tools",and text analysis was carried out according to 63 policy documents.Results: A total of 493 policy codes were completed.From the perspective of policy goals,the policy objectives of Chinese medical insurance payment mainly focused on three aspects: improving the payment level,optimizing the medical insurance environment,and standardizing the supervision regulations.From the perspective of policy tools,environmental policy tools are the most used policy tools,followed by supply and demand tools.There is a shortage of financial input and talent training in all policy objectives,so more attention should be paid to demonstration and Category of payment.Conclusion: Our country puts forth effort to build a perfect medical insurance payment system,but should further strengthen policy content supplement,optimize the structure of policy tools,and give full play to the payment ability of medical insurance when pulling the demand of medical insurance payment and driving the supply of medical insurance payment.
RESUMEN
Objective:To explore the clinical effects of a series of posture intervention strategies on correcting abnormal fetal position, so as to provide a basis for Clinical position management and promotion of natural delivery.Methods:This study was a randomized controlled trial. The convenience sampling method was used to select 196 full-term primiparas women with abnormal fetal orientation confirmed by ultrasound as single fetal head position in the Women′s Hospital, School of Medicine, Zhejiang University from March to October 2022 as the research objects. They were divided into control group 106 cases and research group 90 cases by random number table method. The control group received normal nursing and chose comfortable position by themselves during labor. The research group received a series of ultrasound-guided postural intervention strategies for postural management in the first and second stages of labor on the basis of normal nursing. The angle of progression and the midline angle, the fetal orientation, fetal orientation during complete uterine orifice and delivery outcome were compared between the two groups.Results:Finally, 190 cases were included, 105 cases in the control group and 85 cases in the research group. There were 76 vaginal deliveries in the research group and 95 in the control group. The rate of anterior occipital position and the angle of fetal head rotation in the research group were 73.68% (56/76) and 64.55 (37.90, 85.55)°, which were higher than 45.26% (43/95) and 33.00 (14.00, 60.00)° in the control group;the midline angle of the research group was 57.10(38.50, 75.80)°, which was lower than 80.00 (52.50, 90.30)° of the control group. There was significant difference between the two groups ( χ2 = 14.14, Z = 4.17, - 3.74, all P<0.01). The first stage of labor was 522.50 (413.00, 695.00) minutes and the total stage of labor was 611.00 (488.00, 812.00) minutes in the research group, which was lower than 620.00 (450.00, 795.00) and 700.00 (539.00, 904.00) minutes in the control group ( Z = - 2.34, - 2.03, both P<0.05). Conclusions:The application of the serial position intervention strategy under the ultrasound guidance during the labor process can improve the abnormal fetal position, shorten the first stage of labor time effectively and safely, while it does not have any significant effect on the improvement of the delivery outcome.

AIM: To investigate the short-term visual quality outcomes after femtosecond laser small incision lenticule extraction(SMILE)and evolution implantable collamer lens(EVO-ICL)implantation for the correction of moderate myopia.METHODS: Prospective control study. A total of 51 cases(51 eyes)with moderate myopia who underwent SMILE or EVO-ICL implantation surgery at Weifang Eye Hospital from April 2021 to February 2022 were selected. They were divided into SMILE group(30 patients, 30 eyes)and EVO-ICL group(21 patients, 21 eyes)according to the surgical methods. The changes of visual acuity [uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA)], diopter [spherical equivalent(SE)] and related parameters of optical quality analysis system(OQAS Ⅱ)were observed before surgery and at 1wk, 1 and 3mo after surgery, and the quality of vision(QoV)questionnaire was completed.RESULTS: At 3mo after surgery, the safety index(postoperative CDVA/preoperative CDVA)of SMILE gruop and EVO-ICL group were 1.20(1.00, 1.20)and 1.20(1.00, 1.38), respectively, the efficacy index(postoperative UDVA/preoperative CDVA)were 1.00(1.00, 1.20)and 1.00(1.00, 1.20), respectively, and the percentage of SE within ±0.50D was 87% and 100%, respectively. In SMILE group, the objective scattering index(OSI)was increased after surgery, while modulation transfer function cutoff frequency(MTF cutoff), contrast visual acuity(VA)100%, and VA20% at 1wk and 1mo after surgery, and Strehl ratio(SR)and VA9% at each time point after surgery were all decreased compared with those before surgery(all P&#x003C;0.05). The OSI, MTF cutoff, SR and VA of EVO-ICL group showed no difference at each time point after surgery compared with those before surgery(all P&#x003E;0.05). The most common visual symptoms after SMILE and EVO-ICL implantation were visual haze and halos, respectively.CONCLUSION: Both SMILE and EVO-ICL implantation have good safety, efficacy and predictability in the short term after the correction of moderate myopia. Both groups had visual symptoms after surgery, but the overall satisfaction of patients was high. Furthermore, EVO-ICL implantation has better objective visual quality performance.
RESUMEN
Objective: To explore the stem cell collection rate and efficacy and safety of patients aged 70 and below with newly diagnosed multiple myeloma (MM) treated with the VRD (bortezomib, lenalidomide and dexamethasone) regimen followed by autologous stem cell transplantation (ASCT). Methods: Retrospective case series study. The clinical data of 123 patients with newly diagnosed MM from August 1, 2018, to June 30, 2020, at the First Affiliated Hospital of Soochow University and Suzhou Hopes Hematology Hospital, who were eligible for VRD regimen sequential ASCT, were collected. The clinical characteristics, efficacy after induction therapy, mobilization regimen of autologous stem cells, autologous stem cell collection rate, and side effects and efficacy of ASCT were retrospectively analyzed. Results: Of the 123 patients, 67 were males. The median patient age was 56 (range: 31-70) years. Patients with IgG, IgA, IgD, and light-chain types accounted for 47.2% (58/123), 23.6% (29/123), 3.2% (4/123), and 26.0% (32/123) of patients, respectively. In addition, 25.2% (31/123) of patients had renal insufficiency (creatinine clearance rate<40 ml/min). Patients with Revised-International Staging System (R-ISS) Ⅲ accounted for 18.2% (22/121) of patients. After induction therapy, the rates of partial response and above, very-good partial response (VGPR) and above, and complete response (CR)+stringent CR were 82.1% (101/123), 75.6% (93/123), and 45.5% (56/123), respectively. Overall, 90.3% (84/93) of patients were mobilized with cyclophosphamide+granulocyte colony-stimulating factor (G-CSF) and 8 patients with G-CSF or G-CSF+plerixafor due to creatinine clearance rate<30 ml/min and one of them was mobilized with DECP (cisplatin, etoposide, cyclophosphamide and dexamethasone)+G-CSF for progressive disease. The rate of autologous stem cell collection (CD34+cells≥2×106/kg) after four courses of VRD regimen was 89.1% (82/92), and the rate of collection (CD34+cells≥5×106/kg) was 56.5% (52/92). Seventy-seven patients treated with the VRD regimen sequential ASCT. All patients had grade 4 neutropenia and thrombocytopenia. Among the nonhematologic adverse events during ASCT, the highest incidence was observed for gastrointestinal reactions (76.6%, 59/77), followed by oral mucositis (46.8%, 36/77), elevated aminotransferases (44.2%, 34/77), fever (37.7%, 29/77), infection (16.9%, 13/77) and heart-related adverse events (11.7%, 9/77). Among the adverse events, grade 3 adverse events included nausea (6.5%, 5/77), oral mucositis (5.2%, 4/77), vomiting (3.9%, 3/77), infection (2.6%, 2/77), elevated blood pressure after infusion (2.6%, 2/77), elevated alanine transaminase (1.3%, 1/77), and perianal mucositis (1.3%, 1/77); there were no grade 4 or above nonhematologic adverse events. The proportion of patients who achieved VGPR and above after VRD sequential ASCT was 100% (75/75), and the proportion of patients who were minimal residual disease-negative (<10-4 level) was 82.7% (62/75). Conclusion: In patients aged 70 and below with newly diagnosed MM treated with VRD induction therapy, the collection rate of autologous stem cells was good, and good efficacy and tolerability were noted after follow-up ASCT.

The common reasons for counseling included a history of homosexual behaviors with men (887 clients, 40.23%), non-commercial irregular heterosexual behaviors ( 661 clients, 29.98% ), commercial heterosexual behaviors ( 308 clients, 13.97% ), HIV-positive spouse/regular sex partners ( 123 clients, 5.58% ), and no high-risk behaviors ( 47 clients, 2.13% ). The positive rate of anti-HIV antibody was 2.95% among the 2 205 clients, and a high positive rate was observed among clients at ages of 50 years and below ( 6.15% ), single clients ( 3.71% ), clients with an education level of primary school and below ( 6.04% ) and clients with HIV-positive spouse/regular sex partners ( 11.38% ).@*Conclusions@#Single men at ages of less than 30 years and with a high education level are predominant among VCT clients in Shangcheng District, and a history of homosexual behaviors with men is the predominant reason for counseling. There is a relative low prevalence rate of HIV infection among VCT clients in Shangcheng District; however, a high prevalence rate is found among single visitors at ages of 50 years and older, with an education level of primary school and below and HIV-positive spouse/regular sex partners.
RESUMEN
To investigate the efficacy and safety of total oral regimen containing ixazomib in multidrug-resistant relapsed and refractory multiple myeloma(RRMM). A total of 38 patients were retrospectively analyzed from August 2018 to January 2020 in the First Affiliated Hospital of Soochow University. The overall response rate (ORR)was 36.8%. Among them, the very good partial response (VGPR) or better rate was 23.7%, and the complete response (CR) rate was 5.3%. The ORR was 41.7% in patients receiving ixazomib-lenalidomide-dexamethasone (IRD) regimen. Median PFS was 5 months and median OS was 7.5 months. The ORR was 50% after second-line therapy, 40% after third-line therapy and 12.5% after forth-line therapy or more. The ORR was 29.0% in bortezomib-refractory patients, 38.0% in lenalidomide-refractory patients, 21.4% in bortezmoib & lenalidomide dual refractory patients. Grade 3-4 hematological adverse events (AEs) were reported in 21% patients. Common hematological AEs included lymphopenia, neutropenia, thrombocytopenia. Other usual AEs were fatigue and diarrhea. No grade 3-4 peripheral neuropathy was recorded. In the treatment of relapsed/refractory multiple myeloma patients with multidrug resistance, the total oral regimens containing ixazomib demonstrate reliable efficacy and safety. Early administration of ixazomib at first or second relapse is suggested for more favorable clinical outcome.
RESUMEN
Based on the Global Burden of Disease study 2019, the standardized mortality rate and disability-adjusted life years (DALYs) rate of children under 5 years old were selected as evaluation indicators to compare and analyze the current situation and differences of disease burden of children under 5 years old between China and other regions from 1990 to 2019. The change trend and difference of disease burden of children under 5 years old in China were analyzed by sexes. From 1990 to 2019, the all-cause standardized mortality rate of children under 5 years old in China decreased from 1 153.81/100 000 to 160.39/100 000, and the all-cause standardized DALY rate decreased from 104 426.40/100 000 to 16 479.01/100 000. In 2019, neonatal preterm birth, congenital heart anomalies and lower respiratory infections ranked the top three disease burden of children under 5 years old in China. Except that the disease burden of neonatal preterm birth was lower than that in North America, they were much higher than that in Western Europe and North America in the same period. The burden of unintentional injury diseases, including pulmonary aspiration and foreign body in airway and drowning, was higher than that in Western Europe and North America. The standardized mortality and DALY rate of the top ten diseases and injuries in boys and girls under 5 years old in China showed a downward trend (P<0.05), and most of them were higher in boys than girls (P<0.05). From 1990 to 2019, the disease burden of children under 5 years old in China decreased significantly. However, compared other regions, it is still necessary to strengthen the prevention and control of neonatal premature birth, birth defects and unintentional injuries, and take different sex-specific interventions to improve the overall health of children.

Objective:Taking emergency department (ED) as a starting point, to analyze the epidemiological characteristics and mortality risk factors of sepsis, and to provide evidences for ED to carry out the strategy of "three early and two lower" for sepsis.Methods:Based on the ED and inpatient medical record management information platform of Tianjin Medical University Gernal Hospital, adult ED patients with sepsis from January 1, 2017 to December 31, 2020 were included according to the third international consensus definitions for sepsis and septic shock in 2016 and the consensus of Chinese experts on early prevention and blocking of sepsis in 2020. The epidemiological characteristics of patients were retrospectively analyzed. Chi-square test was used to compare the difference of age, sex, hospitalization times, length of stay, hospitalization cost and infection location between dead patients and survival patients, and a stepwise logistic regression model was used to analyze the influencing factors of mortality in hospitalized patients with ED sepsis.Results:A total of 7 494 patients with sepsis in ED were included in this study, and the annual and monthly component ratios varied from 3.8‰ to 6.1‰ and 2.0‰ to 9.0‰, respectively. The main characteristics of patients with sepsis in ED were as follows: 40-69 years old (46.0%), male (59.0%), mostly diagnosed with sepsis (96.8%), mainly treated with urban health insurance (59.6%), and ED diagnosis and treatment fees of 2 000-8 000 Yuan (51.1%). The mortality of hospitalized patients with ED sepsis was 24.4% and that of hospitalized patients with septic shock was 28.8%. The main characteristics of hospitalized patients with ED sepsis were as follows: most of them were male (56.2%) patients over 70 years old (56.0%), most of them were diagnosed with sepsis (94.0%) and hospitalized for the first time (76.0%), the median hospitalization time was 15 d, most of them were hospitalized under urban health insurance (65.2%), and the median hospitalization fees was 47 000 Yuan. The risk factors of death were influenced by age and length of stay. Patients aged 70 years or older had a higher risk of death than those aged from 18 to 39 years, and patients with a length of stay of more than 7 d had a lower risk of death than those with a length of stay of shorter than 7 d. The primary infection focus were mainly respiratory and urinary systems, while the death rate of patients with hematological and abdominal infections was relatively high, and the difference was statistically significant ( P<0.01). Respiratory and abdominal infections were risk factors for death in patients with ED sepsis. Conclusions:The composition ratio of sepsis in ED patients is not regular in time, so vigilance of sepsis in elderly men and patients with respiratory system, blood system, urinary system and abdominal infections should be constantly raised. Patients with sepsis who are older, hospitalized more frequently, hospitalized for a shorter time, and infected in the respiratory system or abdomen have a higher risk of death.
RESUMEN
Objective:To investigate the effect of Notch on periprosthetic fracture (PPF) of the femoral prosthesis after primary total knee arthroplasty.Methods:A total of 34 patients diagnosed with femoral PPF at Xi'an Honghui Hospital were retrospectively collected from January 2013 to December 2020. There were 4 males and 30 females with a mean age of 69.2±7.2 years (range, 55-84 years). A total of 102 patients without PPF were matched by gender and age as the control group in a ratio of 1∶3. There were 12 males and 90 females with a mean age of 69.2±7.2 years (range, 55-84 years). The main observation indexes included patients' general information and factors such as coronal alignment, prosthesis design and Notch conditions. Then, subgroup analysis was performed with the depth and Tayside classification of Notch to analyze their effects on PPF.Results:The PPF and control groups were comparable in terms of baseline information such as gender, age, body mass index (BMI), and surgical side. There was no significant difference between the two groups in coronal alignment (χ 2=1.019, P=0.601) and prosthesis design (χ 2=1.545, P=0.214). There was no statistical difference in Notch between the PPF and control groups (χ 2=3.548, P=0.060). The mean length of Notch in the PPF group was 4.5±2.7 mm, compared with 4.9±2.8 mm in the control group, with no significant difference between the two groups ( t=0.732, P=0.465). Further subgroup analysis using a Notch depth of 3 mm as a cut-off and Tayside classification revealed a statistical difference between the two groups (χ 2=11.262, P=0.004; χ 2=14.601, P=0.003). Compared with patients without Notch, the risk of PPF was higher when the depth of Notch exceeded 3 mm, with an odds ratio ( OR) of 4.88 (95% CI: 1.76, 13.51). The incidence of PPF was higher when Notch depth reached Tayside grade 3 or 4. Compared with patients without Notch, the risk of PPF would be 6.99-fold (95% CI: 1.85, 26.32) higher when Notch depth reached grade 3. In female patients, there was a significant difference in Notch status between the PPF and control groups (χ 2=3.956, P=0.047), with a higher risk of PPF in female patients with Notch, OR 2.33 (95% CI: 1.01, 5.43). In patients who underwent right-sided TKA, the risk of PPF was higher in patients with Notch compared to those without Notch (χ 2=5.502, P=0.019), with an OR of 3.58 (95% CI: 1.19, 10.75). Conclusion:The Notch has no significant effect on the femoral PPF after primary total knee arthroplasty. However, the risk of PPF will increase significantly when the Notch depth exceeds 3 mm or is above Tayside grade 3.
RESUMEN
AIM: To gather baseline data on visual acuity by screening students from different stages in the same administrative district of Xi'an, as well as to analyze and investigate disparities in myopia rates among students from different stages in this area.METHODS: A total of 13 707 students from 21 elementary schools, 3 middle schools, 3 general high schools and 1 vocational high school were randomly selected for uncorrected distance visual acuity and computerized refraction testing in 28 schools with a random sampling approach.RESULTS: The detection rate of myopia in elementary, middle, high and vocational high schools in the same region of Xi'an were 32.27%, 72.07%, 81.22% and 65.12%, respectively; The total myopia rate of students was 47.81%; The myopia rate of girls was higher than that of boys in all grades; The myopia rates of elementary and middle schools increased with the growth of grades; The percentage of high myopia increased from 2.40% in elementary schools to 16.51% in high schools with the growth of grades.CONCLUSION: The myopia rate in different stages of the same region is different, and it tends to rise with the gronth of grades; Girls have a higher myopia rate than boys; Compared to the results of the national survey on myopia in different grades of children and adolescents in 2018, the myopia rate in the same region has decreased significantly in 2021 of the elementary school level, although myopia rate of middle school and high school stage do not rise, the decline is not obvious.
